Synthesis of Copolymer from 1,3,5-Trioxane and ε-Caprolactone Catalysed by Treated Bentonite as Eco-Catalyst

This study presents a novel green method for copolymerizing 1,3,5-trioxane (TOX) with ε caprolactone (CL). This technique uses Maghnite-H+ (Mag-H+) as a bulk green catalyst. Various techniques were used to confirm the structure of the resulting copolymer. The influencing factors on the copolymerization reaction were also studied. The results show that the best copolymer yield (46.3 %) was obtained via bulk copolymerization at a temperature of 353 K for a reaction time of 8 h.

The cross linked polyesters based on glutamic acid, glycerol and oxyethylene and oxypropylene alcohols were received. It was shown that those polyesters are able to form stabilized dispersion with microsized particles. Отримано перехресно зшиті поліестери на основі глутамінової кислоти, гліцерину та спиртів оксиетиленового та оксипропіленового ряду. Показано що такі поліестери здатні формувати стабільну дисперсію з частинками мікронного розміру
